Connected plurality of twisted wire mascara brushes

ABSTRACT

A plurality of twisted wire mascara brushes connected along the lengths of their perspective metal cores, yielding zones on the plurality of brushes that has bristles from only one brush, and zones where the fibers intermingle from the plurality of brushes. This creates different zones of fiber density, the low fiber density zones will apply the mascara while the higher density fiber zones will comb and separate the lashes. This plurality of connected twisted mascara brushes is attached to a single stem.

BACKGROUND

This invention relates to an applicator for a pastry cosmetic product, notably mascara.

BACKGROUND OF THE INVENTION

The invention relates an applicator for a pastry cosmetic product notably mascara.

The purpose of a mascara applicator is to apply a rich coat of mascara to the eyelashes, while separating and lengthening them. Traditional mascara brushes are composed of a single twisted wire which fixes the bristles between them in a helical array. Due to the high viscosity of mascara, which is necessary to lay a thick coating on the lashes, mascara has a tendency to clump the lashes together and give an uneven application of the product on the lashes. Mascara brushes with a density of fibers too low will apply too much mascara on the lashes and lead to clumping of the lashes and uneven distribution while mascara brushes with a high density of fibers will not apply sufficient quantity of mascara on the lashes. A similar trade-off is made while selecting the flexural strength of the brushes. Soft fibers (ones with a low flexural strength) apply mascara to the lashes but do not separate the lashes, because they simply flex and do not resist enough to penetrate the lashes well enough to comb the lashes. Stiffer fibers (fibers with a relatively high flexural strength) lengthen and separate the lashes well, but do not do a good job of applying mascara to the lashes. Clearly there exists a need for a mascara brush that both separates the lashes, and transfers a rich quantity of mascara to the lashes.

BRIEF SUMMARY OF THE INVENTION

This invention consists of two spiral mascara brushes connected along the lengths of their perspective metal cores. The advantage of that simple concept gives to the application of mascara is first that around the circumference of the brush the density of fibers will vary. In the parts of the brush where there is no overlapping of the brushes, the fiber density will be low, giving more volume to the lashes. In the zones of the brush where the brushes do overlap and the fibers from each of the two brushes intermingle there will be a higher density of fibers, resulting in a better combing and separation of the lashes. Both zones are necessary to optimize the application of mascara, one zone that yields volume and another zone that separates and extends the lashes. Also a grip placed on the handle would aid the user to orient the brush correctly, so that the lashes would first pass through the zone with the low fiber density, then be combed when they pass through the high density fiber zone.

Another possibility that this invention opens up is that besides having a different fiber density the double brush can be made of two brushes with fibers of different flexural strength. For example one twisted brush can have fibers of low flexural strength that deposit a rich quantity of mascara on the lashes, while the second brush can be made of fibers with a higher flexural strength to comb and separate the lashes. This could also be in combination with brushes having a different fiber density to optimize the application, combing, and separating of the lashes.

This invention has a zone of the brush that serves to coat the lashes and another that serves to separate the lashes. In every pass of the mascara brush, the lashes are exposed to and immersed in both of these zones.

U.S. Pat. Nos. 6,397,855 and 6,408,857 show a mascara brushes configured in a loop, being they are configured in a loop, this signifies that there is a distance between the two sections of the brushes. The bristles from each section do not intermingle throughout the length of this brush, as in the present invention.

U.S. Pat. Nos. 5,611,361, 4,600,328, and 5,052,839 show a plurality of applicators; however these applicators are spaced apart from each other, on different stems or tines, not connected.

The purpose of these applicators is to coat the lashes from each side, whereas the purpose of the present invention is to provide one zone of the brush that will provide volume and another zone of the brush to comb, and separate the lashes.

U.S. Pat. No. 4,458,701 also shows a dual brush mascara applicator. In this applicator, the brushes are separated, and on stems. The method of application is by placing the eyelashes in-between the two brushes, and squeezing the brushes together. Aside from being difficult to do, this method does not yield two separate zones of bristle density.

U.S. patent application Ser. No. 2003084913 shows two mascara brushes twisted around each other; these twisted mascara applicators will not provide one clear zone for the lashes to enter, thus giving volume, and another giving separating. Since the bristles from both brushes are randomly intermingled, where the bristles are, it will act like one brush, without having zones of different fiber density. Also this brush is different from the present invention because it states that the cores of the brushes are separated at a distance, where in the present invention, the cores of the brushes are connected.

DETAILED DESCRIPTION OF THE INVENTION

As show in FIG. 1, this invention consists of two spiral mascara brushes connected along the length of their metal core. This connecting of 2 mascara brushes along the length of their cores yields 3 different zones of the dual brush. The zone of the dual brush (15) where there are only bristles from brush A, the zone of the dual brush (16) where there are only bristles from brush B, and the zones of the dual brush where there are bristles intermingling (14) from brush A and B. Zones where there are the bristles from both brushes will work to give good separating and combing to the lashes. The zones with the bristles from both A and B will have a relatively higher bristle density of fibers with respect to zones where there are only bristles from one of the mascara brushes. The mascara brushes A and B may, but need not be identical. If they are not identical this would create 3 different zones on the mascara brush corresponding to 3 different types of application characteristics. In one embodiment brush A has bristles of 3 mils which do an excellent job of coating the lashes and brush B has bristles of 11 mils which do an excellent job of separating the lashes. The users would pass both these zones across her eyelashes to get the benefits of both types of bristles in one stroke.

In another embodiment of this invention, the two twisted wire brushes that make up this invention would be identical, creating 2 different zones of the mascara brush, one with a relatively low density of fibers. The zone with the relatively low density of fibers would apply a rich coat of mascara to the lashes. The zones where the brushes intermingle would have a relatively higher density of fibers, thus, combing and separating well the lashes.

One more advantage of this invention is that it facilitates a way to make a mascara brush with 2 different lengths of fibers. The longer fibers help in combing the lashes while the shorter fibers help in applying the mascara on the lashes. Many inventions have shown way of producing a brush with fibers of different length, however the process to make these brushes have always been more complicated than use two brushes connected lengthwise along their perspective lengths.
